Filed: 1988-02-02
Abstract: PURPOSE:To narrow the width of a current injection region, to lower a threshold current value and to stabilize laser oscillation by forming a projecting section in which the width of a lower section is made narrower than an upper section. CONSTITUTION:An N-type clad layer 3, an active layer 4, a P-type clad layer 5 and a P<+> type cap layer 6 are grown successively onto the face (100) of an N-type GaAs substrate 2. A resist is shaped so that the striped direction is directed in <011>, and etching is conducted by an etchant at the ratio of H2SO4:H2O2:H2O=1:8:1. Consequently, the side faces of a projecting section left under the resist are represented by a face (1-11) and a face (11-1), and the striped projecting section 5 in which a lower section is made narrower than an upper section is formed. An SiO2 layer 8 is shaped, the SiO2 layer on the layer 6 is removed, and electrodes 1, 7 are formed. Since the width of the lower section of the projecting section 5 is narrowed, current injection width can be narrowed. Sections except the cap layer 6 are coated with the SiO2 layer 8, thus also preventing leakage currents.

Title: Method and device for erecting blades of multiblade saw
Inventor: MINAMIYAMA TAKAYUKI
IPC: B23D51/08
Filed: 1980-02-28
Abstract: PURPOSE: To heighten the accuracy of cutting-off, by clamping each blade under a force smaller than the clamping force of a pinch-holding member, at both ends of the blade whereon spacers are arranged.  
     CONSTITUTION: The plural blades 11 and pinch-holding members 12 of a multiblade saw are fitted in the groove 21 of a wall 20a and secured together by the first clamping means 24 composed of contact metal members 14 and lockup bolts 22. A spacer 13 is provided between the pinch-holding members 12. Since the blades 11 are erected along the spacers 13, the blades 11 are prevented from becoming nonparallel with each other due to the deformation of the members 12. The degree of parallelism between the blades 11 is thus heightened. The spacers 13 and the blades 11 can be clamped into tight contact with each other because the blades 11 are clamped by the clamping means 25 of a restrictor composed of the spacers 13 and the second clamping members 25 after the blades 11 are pulled. This results in heightening the accuracy of cutting-off.
